# Fun-ASR-Nano-2512 GGUF

Standalone audio.cpp GGUF builds of
[FunAudioLLM/Fun-ASR-Nano-2512-hf](https://huggingface.co/FunAudioLLM/Fun-ASR-Nano-2512-hf).
Each file embeds the model configuration, processor configuration, tokenizer,
chat template, and the audio.cpp model package specification.

The source checkpoint is pinned to revision

## audio.cpp

```bash
audiocpp_cli \
  --task asr \
  --family fun_asr_nano \
  --model fun-asr-nano-2512-q8_0.gguf \
  --backend cuda \
  --audio speech.wav
```

Fun-ASR-Nano currently provides offline multilingual ASR. It does not expose
streaming or timestamp output. On CUDA, audio.cpp keeps the Q8_0 encoder and
adaptor weights native and loads decoder weights as BF16 by default for stable
logits. An explicit `fun_asr_nano.decoder_weight_type` session option overrides
that default.

## Reproducibility

The files were generated with audio.cpp's `audiocpp_gguf` converter:

```bash
audiocpp_gguf \
  --input model.safetensors \
  --root /path/to/Fun-ASR-Nano-2512-hf \
  --output fun-asr-nano-2512-q8_0.gguf \
  --type q8_0 \
  --family fun_asr_nano \
  --model-spec model_specs/fun_asr_nano.json
```

Both formats were checked with `audiocpp_gguf --inspect` and full reference
audio transcription on CPU and NVIDIA H100 CUDA.
